Agatha Christie's Masterpieces - Detective Fiction

In the novel "Cards on the Table", an eccentric and wealthy collector invites four master sleuths—including Hercule Poirot—and four suspected murderers to a bridge party, only to be stabbed to death in plain sight while the guests are playing. Poirot must analyze the psychological traits of the players and study the bridge scorecards to deduce which of the four suspects committed the perfect crime.
